FPC flex printed circuits board process includes exposure, PI etching, opening, electrical testing, punching, appearance testing, performance testing, etc. The FPC flexible board production process is related to the performance of the FPC, after the completion of the production it needs to be tested to screen out the unqualified FPC flexible board, to ensure that […]
First, artificial soldering iron welding (manual soldering)Manual soldering flexible board in the circuit board is the most inexpensive process of all flexible board soldering processes, some even do not need to use the jig can work, but the quality of its soldering is also one of the most unreliable processes because manual soldering is easy […]
Soldermask is printed on the surface of the PCB with a layer of ink, which plays an insulating role, but also a role in protecting the copper surface, playing a role in beautiful and beautiful, it is like wearing a piece of clothing on the outside of the PCB, so it's extremely easy to find […]
FR-4 epoxy glass fiber cloth substrate is a class of substrate with epoxy resin as a binder and electronic grade glass fiber cloth as reinforcing material. Its bonding sheet and the inner core of the thin copper-clad laminate, make the production of multilayer printed circuit boards an important substrate. FR4 is a flame-resistant material grade […]
Flexible PCB, FPC PCB, made of polyimide or polyester film as the base material, is a highly reliable and excellent flexible printed circuit board. It is mainly used in cell phones, laptops, PDAs, digital cameras, LCMs, and many other products - FPC Test The production of a good quality FPC board must have a complete […]
Alumina ceramic PCB is a special process board in which copper foil is bonded directly to the surface of alumina (Al2O3) ceramic substrate (single-sided or double-sided) at high temperature. The ultra-thin composite substrate is made of excellent electrical insulation properties, high thermal conductivity characteristics, excellent soft brazing, and high adhesion strength, and can be etched […]
The development trend of the electronic information industry requires more and more PCBA assembly processes, and the reliability and quality of electronic machine products are mainly determined by the reliability and quality level of PCBA. electronic pcb assembly Residues on PCBA mainly come from the assembly process, especially the welding process. Such as the use […]
After ensuring that the PCB does not have a short circuit, broken circuit, poor contact, and other bad problems, before packaging and shipping. circuit board light fixture Test Methods have two:1. Flying probe test2. Fixture test. The flying probe test is one of the methods to check the electrical function of PCB (open and short […]
Metal-based PCBs, also known as Metal Core PCBs (MCPCBs), are classified into five primary categories based on their structure and application. metal circuit board These categories include:Single Layer MCPCBChip-On-Board (COB) MCPCBDouble Layer MCPCBDouble-Sided MCPCBMultiple Layer MCPCB Single layer MCPCBs feature one conductive trace layer on one side of the board and a metal substrate, typically […]
Design and PlanningThe initial step in PCB production is the design of the board. Designers use specialized PCB design software to create a blueprint that captures all necessary circuit layouts and specifications. Before moving to fabrication, it's essential to ensure that the design is compatible with the manufacturer’s capabilities, including informing them about the software […]
PCB prototypes are an essential phase in the development of electronic devices. They allow designers and engineers to validate the functionality and performance of a circuit board before mass production. By creating prototypes, potential design flaws can be identified and corrected, which reduces costs and enhances the likelihood of a successful final product. pcb board […]
Printed Circuit Boards (PCBs) are fundamental components in the electronic devices that define modern technology. They provide the mechanical and electrical backbone for a vast array of devices, allowing components to communicate and function as intended. With advancements in technology, the ways in which PCBs are designed, manufactured, and colored have evolved, showcasing the intricacies […]
